ATyS g M are modular automatic transfer switches with positive break indication. They are 2 or 4 pole (single or three-phase) devices.
They have all the functions of the ATyS d M together with an integrated controller, giving them automatic features dedicated and mains/genset applications. They are intended for use in low voltage power supply systems where a brief interruption of the load supply is acceptable during transfer.
ATyS g M transfer switches offer significant time saving during commissioning (the process takes 2 to 3 minutes). Thanks to
the design that allows commissioning through through just 4 potentiometers and four DIP switches, a screwdriver is all that is required to configure the parameters.
Dedicated to mains/genset applications
In addition to its single-phase and threephase voltage & frequency monitoring for both incoming sources, the product’s integrated controller also features functions that are specific to mains/genset applications (genset control, test on load, etc.).
To ensure that the correct configuration is maintained an optional sealable cover can be fitted in order to avoid any unintentional modifications to the programming.
ATyS g M have both electrical and mechanical interlocks for optimum security. They also feature a positive break indicator, confirming switch position with dual mechanical indicators for increased safety.
ATyS g M devices are based on a coil solution with rotating contacts, therefore ensuring an extremely short black-out duration (< 90ms).
Superior electrical performance
ATyS g M devices are compliants with IEC 60947-6-1, the standard governing transfer switches. Their AC-33B properties of up to 125 A mean you can use the same product for resistive and inductive loads.
Immune to voltage fluctuations
The power supply of the ATyS g M is only active during transfer. As the product is based on stable positions, it is not affected by network voltage fluctuations.
